This linkage type fire alarm controller mainly to be used in middle and big size fire fighting project. It is the fire fighting master.

1. Adopting the peer-to-peer structure with no master slaver system to design, each controller can display the working condition of all equipments in the network.2. Super large scale on the unit capacity: 4~64 loops, 300~16384 addressable codes, can load with manual panels.3. Network capacity: 64 sets of controllers, 256 loops, 65536 addressable codes, 64 manual control panels.4. Which can be interconnected with other building equipments through LD6900 series communication module (CAN Bus, RS232, RS485, Ethemet, telephone line, GPRS).5. Adopts the RISC embedded system based on the ARM platform, low power consumption, and fast processing speed and stable operation.6. Adopts the real-time multitask embedded operating system, the response time is short.7. Adopts modulariztion power design, insulating each other, decrease the load of the single power supply, improves the whole performance of the controller.8. Adopts 24 bits real color 12.1 inch LCD, numerous graphic functions, which can display the plan and graphic chart, with LED indicating the key state.9. Adopts touch screen, operating conveniently and flexibly, also can extend to the mouse and keyboard operation.10. Equipt with the recording function (like black box), which can keep 1000 piece of fire records. 1000 piece of fault records,, 1000 piece of request records, 1000 piece of starting records, 1000 piece of feedback records, 1000 piece of personel operaton records and 1000 piece of monitoring alarm records.11. Coding automatically matching with the bus equipments, recording the smoke/temperature output curve and data. Coding easily. Threshold value can be set by manual. Controller display all fire alarm plans in network.12. Which has supervision alarm function, it can monitor the alarm in formation of the field leakage current, and also can control the leakage current break automatically.13. With the loop short circuit protection function and power supply short circuit protection.
